CALVIN \V. VAUGHN, OF OUYAIIOGA FALLS, OHIO, ASSIGNOR TO THE TURNER,VAUGHN & TAYLOR COMPANY, OF SAME PLACE.

MACHINE FOR MAKING BESSEMER-CONVERTER NOZZLES.

SPECIFICATION forming part of Letters Patent No. 426,084, dated April22, 1890.

Application filed December 4, 1889 Serial No. 332,539. (No model.)

To all whom it may concern:

Be it known that I, CALVIN \V. VAUGHN, a citizen of the United States,residing at Cuya hoga Falls, in the county of Summit and State of Ohio,have invented a certain new and useful Improvement in Machines forMaking Bessemer-Converter Nozzles, of which the following is aspecification.

My invention has relation to improvements in machines for forming fromground and tempered silica or other analogous material the nozzlesthrough which. the metal flows from the converters in the Bessemensteelprocess, but may be employed in the construction of other articlescomposed of compressed plastic material.

The objects of my invention are to secure rapid and intense compressionof the plastic material, to eject the completed article from the mold,and generally to simplify the construction and. reduce the number ofparts.

To these ends my invention consists in the peculiar construction andcombination of parts hereinafter described, and then specificallypointed out in the claims, reference being had to the accompanyingdrawings, which form a part of this specification.

I11 the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is a front elevation of my improvedmachine 3 Fig, 2, a side elevation of the same; Fig. 3,21, detached sideelevation of the revolving core and its driving mechanism, and Fig. at acentral. vertical section of the mold and connected. parts in the planeof the lift ing-rods.

Upon a frame A is mounted a cylinder 13, containing a piston, which maybe operated. by steam, water, or other agent, the pistonrod of whichextends through the upper cylinder-head and carries a crosshead O.

The operation of the piston is regulated by a valve D, operated by ahand-lever E, pivoted to the frame A.

Depending from the cross-head O are parallel rods F F, which connect attheir lower ends with a cross head or yoke G, carrying a hollow shaft H,which slides in a tubular guide I, attached to the base of the frame A,and moves in alignment with the cylinder B.

Upon the yoke G is amold J to form the exterior of the nozzles, insideof which is a plunger K, attached to the upper end of a rod L, whichpasses through the hollow shaft H, and has its lower end connected withacross head or yoke M. From the ends of the yoke M two parallel rods N Nproject upward through the base of the frame A and the brackets O O, andat their upper ends bear nuts, by which the distance between thebrackets and yoke M may be adjusted.

The plunger K consists of a cylinder (or prism, if the interior of themold be a polyhedron) accurately fitted to slide in the mold J, and ofsuch length that when its base rests on the yoke G its top will rest inthe lower end of and constitute a bottom for the mold. In the top ofthis plunger is a tapering depression P, less in diameter and locatedcen trally within the mold to form a tapering tenon on the lower end ofthe nozzles, in the bottom of which depression is a central orifice Q toreceive the core hereinafter referred to, and beneath this orifice achamber R to receive any surplus material that may be pressed out of themold by the core. It will be obvious, however, that the form of thisplunger will vary with the form of article to be pressed, its functionsbeing twofold-viz., to constitute a bottom for the mold. and to push thecompleted article from the mold.

Below the cylinder B is journaled in suit able bearings attached to theframe A and in alignment with the axis of the cylinder and mold a shortvertical shaft S, bearing a bevel-gear T, which meshes with a similarbevel-gear U on one end of a horizontal shaft V, on the other end ofwhich is a pulley TV.

To the lower end of the shaft S is attached by any suitable device acore Y, consisting of a pointed shaft to form the orifice in the tuyere.

The mold J and plunger K, with their immediately connected parts, are soarranged that when the yoke G is at the end of the downward stroke ofthe piston the rods N N, arrested by the brackets O 0, will sustain theplunger K at the upper end of the mold with in Figs. 1 and 2.

In operation the core Y is caused to revolve rapidly by power conveyedto the pulley W. Steam is applied to the cylinder and the mold J raisedsufficiently to permit the plunger K to descend by gravitation to thebottom in the position shown in Fig. 4, when the mold is charged withthe material to be operated upon. Steam is again applied and the moldraised until the core enters the chamber R, by which operation thematerial is compressed between the mold and core to the desired shape.The motion of the piston is reversed and the mold descends with thecompleted article until the nuts on the rods N N encounter the bracketsO O and arrest the downward movement of the plunger K, which, as themold continues to descend, forces the completed article upward until atthe end of the stroke it stands on the plunger at the top of the mold,whence it is removed by hand.

I claim as my inven tion The combination, with the lifting-cylinder andits piston-rod, of the yoke 0, connectingrods F F, yoke G, bearing themold J and hollow shaft H, the plunger K, shaft L, yoke M, rods N N, andbrackets O 0, all constructed and arranged substantially as shown, andfor the purpose specified.

In testimony that I claim the above I here.
